This chapter briefly reviews the present state of judgment aggregation theory and tentatively suggests a future direction for that theory. In the review, we start by emphasizing the difference between the doctrinal paradox and the discursive dilemma, two idealized examples which classically...

Recent uprisings in the Arab world consist of individuals revealing vastly different preferences than were expressed prior to the uprisings. This paper sheds light on the general mechanisms underlying large-scale social and institutional change. We employ an agent-based model to test the impact...

This paper develops and offers the theory of embodied social presence (ESP). The paper reviews the literature on place and space, presence, and embodiment and demonstrates that the role of the body as a focal point for action during social interaction in multi-user virtual environments has been...

This chapter examines how the original tenets of the affect-as-information hypothesis can be extended to explain a wide range of judgment phenomena, especially with respect to consumer decision making. To this end, research within social psychology as well as research from other fields such as...

Over the course of three hundred years, the institutional organization of the Christian church evolved from small loosely organized groups meeting in house churches to a form of hierarchical organization known as monepiscopacy. Monepiscopacy denotes a form of ecclesial polity in which a single...

A Bayesian agent evaluates a stream of information over a finite period before deciding on which of two alternatives to adopt. At any point, the agent is free to convert information into an informative, binary signal. When information arrives at a roughly constant rate, an agent who frequently...

We analyze a discrete-time search problem in which committee members inspect alternatives sequentially over a finite search horizon. A collective decision to stop searching and accept the current alternative is reached when it is supported by a threshold number of individual votes. We...

This paper questions the conventional wisdom that publication bias must result from the biased preferences of researchers. When readers only compare the number of positive and negative results of papers to make their decisions, even unbiased researchers will omit noisy null results and inflate...

A policymaker selects a group of citizens—a minipublic—to advise her on the desirability of a policy. Each citizen can discover local evidence about the policy but might prefer not to due to political uncertainty in the policymaker’s adoption threshold. Such uncertainty is detrimental to...

Informed voters are believed to be necessary for the well-functioning of elections. However, the puzzle is raised: Why are voters and politicians becoming more polarized despite the increased availability of information? We consider an election with policy-motivated candidates and partially...
